HINGE. I

Specification of Letters Patent.

Patented Sept. 5, 1916.

Application filed July 8, 1916. Serial No. 108,190.

To all whom it may concern:

Be it known that I, GEORGE W. HADEN, a citizen of the United States, residin at Detroit, in the county of Wayne and tate of Michigan, have invented certain new and useful Improvements in Hinges, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to an improved hinge and has for its primary object to provide a very simple and durable concealed hinge for the sectional hood cover of an au tomobile engine.

It is one of the more articular objects of the inventionto provi e an -improved construetion of the edges of the sheet metal hood sections which are connected by the pintle or hinge rod whereby a substantially self-supported water and dust-proof hinge is obtained.

It is a further general object of the invention to devise a hinge for automobile hoods which may be constructed in any desired length and at comparatively small cost and which will be very serviceable and efiicient in practical use.

With the above and other objects in view, my invention consists in the novel features of construction, combination and arrangement of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawing, in which,

Figure 1 is a transverse SGCtlOIlfilVlGW through the two sections of an automobile hood, illustrating my improved hinge; Fig. 2 is a top plan view with certain parts broken away; and Fig. 3 is a detail fragmentary perspective view of the hingedly connected edges of the hood sectlons.

Referring in detail to the drawing,5 and 6 designatethe sheet metal sectlons of the engine hood of an automobile. These hood sections may be of any necessary length and the longitudinal edge of the section 5 is bent upon itself as indicated at"7, to provide a longitudinally extending portion lying inclose contact with the concave bottom face of said hood section From this portion 7 of the sheet metal section, the same is ex tended downwardly and outwardly in the form of a substantially semi-circular gutter or trough 8. At the outer edge of this longitudinal gutter, the metal is laterally -ex tended inwardly, as at 9, and is provided upon its inner edge with a plurality of spaced knuckles 10, the longitudinal axes of which are coincident with the vertical central line of the trough 8.

The other section 6 of the sheet metal hood also has its longitudinal edge bent upon itself, as shown at 12, such bent edge of the metal plate being slightly offset from the body of the plate, as at 18. Upon the inner edge of the returned portion 12 of said plate, a series of spaced knuckles Mare formed.

In assembling the two sections of the hood 6 is inserted between the returned portion 7 of the hood section '5 and the longitudinal lmuckle 10 thereon, and normally underlies the portion 7 which is in contact therewith, as .shownin Fig. 1. The spaced knuckle sections on the hood section 6 fit between the spaced knuckle sections 10 of the hood section 5 and are disposed in alinement therewith. These alined knuckle sections receive the pintle rod 16, whereby the two hood sections are connected. When the hood is closed and the sections 5 and 6 thereof are disposed in the same plane, the offset 13 on the hood section 6 abuts tightly against the edge of the returned portion.7 on the hood section 5, and effectually prevents. the entrance of water, dust or dirt between the portions 7 and 12 of the hood section. When the hood is opened, the section 6 thereof is swung outwardly and upwardly upon the pintle rod 16. The wall of the trough or gutter 8 and the portion 9 thereof affords a substantial brace or support for the edge of the hood section 6 and the pintle rod 16, and the portion 12 of the hood section -6 in turn limits the downward movement of the hood section 6 to its closed position and obviates the possibility of bending or distortion of the hingedly connected edges of the hood sections. Thus the hinge is, in effect, self-supported, and no additional means of support for the pintle rod 16 is required. The trough 8 forms a collecting gutter for any rain waterwhich may find its way between the contacting portions 7 and 13 of the two hood sections, and said trough may have its base wall slightly inclined to discharge the water through suitable openings provided in one of the end Walls of the hood. Thus, the entrance of water to the or cover, the portion 12 of the hood section connection with the accompanying drawing, the construction, manner of operation and several advantages of the invention will be clearly and fully understood.

The device is exceedingly simple and durable in its construction and does not materially add to the cost of the ordinary engine hood as now provided upon motor vehicles. The hingedly connected edges of the hood sections may be readily bent or formed into the desired shape by an ordinary metal bending machine. lit is manifest, of course, that while I have shown and specifically described the preferred form and construction of the several features of the device, the same is, nevertheless, susceptible of considerable modification therein and I, therefore, reserve the privilege of adopting all such legitimate changes as -may be fairly embodied within the spirit and scope of the invention as claimed.

Having thus fully described my invention, what I desire to claim and secure by Letters Patent is 1. A; hinge of the character described including two sheet metal parts, one of said parts being bent upon itself to provide a series of spaced knuckles extending in parallel spaced relation to one of the longltudinal edges of said part, the other sheet metal part being offset and bent upon itself adja cent one of its longitudinal edges, said returned portion of the sheet metal part having a series of spaced knuckles formed therein, said oflset portion of the latter part being adapted for engagement beneath the longitudinal edge of said first named part and the knuckles thereon being disposed in axial alinement with the knuckles on said first part, and a hinge rod extending through the alined knuckles.

2. A. hinge of the character described including two sheet metal parts, one of said parts being bent to provide a longitudinally extending trough in one edge thereof and having a flange projecting inwardly from the outer edge of said trough and provided with a plurality of spaced knuckles disposed in parallel spaced relation to the longitudinal edge of said part, the other of said sheet metal parts being also provided with a series of spaced knuckles arranged in axial alinement with the knuckles on the first part, and a hinge rod connecting said knuckles, said second part having means acting to limit the relative movement of said hingedly connected parts.

' 3. A hinge of the character described including sheet metal parts 5 and 6, the part 5 having a returned portion 7 and a longitudinally extending, outwardly curved i wall 8, a flange 9 projecting inwardly from the edge of said curved wall and knuckle sections 10 formed on the edge of said flange in spaced relation to the returned part 7, the other of said sheet metal parts having an oflset formed therein and being returned upon itself, as at 12, and formed on the inner edge of said returned part with knuckle sections 14, the said latter part overlying the flange 9 on the first named part and the portion 12 extending beneath the portion 7 of said first named part, said knuckle sections being alternately arranged in axial alinement, and a hinge rod 16 conmeeting said knuckles.

4:. A hinge of the character described including two parts, one of which is formed with a trough having a flange extending inwardly from one of its longitudinal edges provided with spaced knuckles thereon, the other of said parts overlying said flange and normally closing the open side of the trough, said latter part being provided upon its under side with spaced knuckles for engagement between the knuckles on the trough flange, and a hinge rod extending through the alined knuckles.

5. A hinge of the character described including two parts, one of which is provided with a trough having flanges projecting inwardly from its longitudinal edges, a series of spaced knuckles formed upon one of said flanges, the other of said parts overlying the latter flange and projecting beneath the other flange of the trough to normally close the open side thereof, said latter part being also provided with spaced knuckles on its under side in alinement with the knuckles on the trough flange, and a hinge rod extending, through the alined knuckles.

lln testimony whereof I hereunto aflix my signature in the presence of two witnesses.
